RESUMO
BACKGROUND AND AIMS: Surgical explantation of transcatheter heart valves (THVs) is rapidly increasing, but there are limited data on patients with THV-associated infective endocarditis (IE). This study aims to assess the outcomes of patients undergoing THV explant for IE. METHODS: All patients who underwent THV explant between 2011 and 2022 from 44 sites in the EXPLANT-TAVR registry were identified. Patients with IE as the reason for THV explant were compared to those with other mechanisms of bioprosthetic valve dysfunction (BVD). RESULTS: A total of 372 patients from the EXPLANT-TAVR registry were included. Among them, 184 (49.5%) patients underwent THV explant due to IE and 188 (50.5%) patients due to BVD. At the index transcatheter aortic valve replacement, patients undergoing THV explant for IE were older (74.3 ± 8.6 vs. 71 ± 10.6 years) and had a lower Society of Thoracic Surgeons risk score [2.6% (1.8-5.0) vs. 3.3% (2.1-5.6), P = .029] compared to patients with BVD. Compared to BVD, IE patients had longer intensive care unit and hospital stays (P < .05) and higher stroke rates at 30 days (8.6% vs. 2.9%, P = .032) and 1 year (16.2% vs. 5.2%, P = .010). Adjusted in-hospital, 30-day, and 1-year mortality was 12.1%, 16.1%, and 33.8%, respectively, for the entire cohort, with no significant differences between groups. Although mortality was numerically higher in IE patients 3 years postsurgery (29.6% for BVD vs. 43.9% for IE), Kaplan-Meier analysis showed no significant differences between groups (P = .16). CONCLUSIONS: In the EXPLANT-TAVR registry, patients undergoing THV explant for IE had higher 30-day and 1-year stroke rates and longer intensive care unit and hospital stays. Moreover, patients undergoing THV explant for IE had a higher 3-year mortality rate, which did not reach statistical significance given the relatively small sample size of this unique cohort and the reduced number of events.

PURPOSE OF REVIEW: To provide a comprehensive summary of relevant studies and evidence concerning the utilization of different pharmacotherapeutic and revascularization strategies in managing coronary artery disease and acute coronary syndrome specifically in the older adult population. RECENT FINDINGS: Approximately 30% to 40% of hospitalized patients with acute coronary syndrome are older adults, among whom the majority of cardiovascular-related deaths occur. When compared to younger patients, these individuals generally experience inferior clinical outcomes. Most clinical trials assessing the efficacy and safety of various therapeutics have primarily enrolled patients under the age of 75, in addition to excluding those with geriatric complexities. In this review, we emphasize the need for a personalized and comprehensive approach to pharmacotherapy for coronary heart disease and acute coronary syndrome in older adults, considering concomitant geriatric syndromes and age-related factors to optimize treatment outcomes while minimizing potential risks and complications. In the realm of clinical practice, cardiovascular and geriatric risks are closely intertwined, with both being significant factors in determining treatments aimed at reducing negative outcomes and attaining health conditions most valued by older adults.

PURPOSE OF REVIEW: This review explores the epidemiology, clinical traits, and diagnosis of Transcatheter Aortic Valve Replacement-Associated Infective Endocarditis (TAVR-IE) and mitral transcatheter edge-to-edge repair infective endocarditis (TEER-IE), focusing on a multimodal imaging approach. It addresses the rising prevalence of TAVR and TEER, emphasizing the need to understand long-term complications and clinical consequences, which poses significant challenges despite advancements in valve technology. RECENT FINDINGS: Studies report a variable incidence of TAVR-IE and TEER-IE influenced by diverse patient risk profiles and procedural factors. Younger age, male gender, and certain comorbidities emerge as patient-related risk factors. Procedure-related factors include intervention location, valve type, and technical aspects. Microbiologically, Staphylococcus aureus, Viridans Group Streptococcus, and Enterococcus are frequently encountered pathogens. TAVR-IE and TEER-IE diagnosis involves a multimodal imaging approach due to limitations in echocardiography. Blood cultures and imaging aid identification, with Fluorescence in situ hybridization is showing promise. Treatment encompasses medical management with antibiotics and, when necessary, surgical intervention. The management approach requires a multidisciplinary "Endocarditis Team." This review underscores the need for continued research to refine risk prediction, enhance diagnostic accuracy, and optimize management strategies for TAVR-IE, considering the evolving landscape of transcatheter interventions.

BACKGROUND: Paravalvular regurgitation (PVR) may be missed intraoperatively with transthoracic echocardiography (TTE) guided minimalist TAVR. We sought to determine the incidence and echocardiographic distribution of PVR missed on intra-op TTE, but detected on predischarge TTE. METHODS: From July 2015 to 2020, 475 patients with symptomatic severe native aortic stenosis underwent TTE-guided minimalist TAVR. Missed PVR was defined as predischarge PVR that was ≥1 grade higher than the corresponding intra-op PVR severity. PVR was classified as anterior or posterior on the four standard TTE views; parasternal short-axis (PSAX), parasternal long-axis (PLAX), apical 3-chamber (A3C), and 5-chamber (A5C). Location-specific risk of missed PVR was then determined. RESULTS: Mild or greater PVR was seen in 55 (11.5%) cases intra-op and 91 (19.1%) at predischarge, with no severe PVR. Among the 91 patients with ≥mild predischarge PVR, missed PVR was present in 42 (46.2%). Compared to the corresponding anterior jets, missed PVR rate was significantly higher for posterior jets in PLAX (62.5% vs. 25.0%, p = 0.005), A5C (56.9% vs. 25.0%, p = 0.009), PSAX (66.7% vs. 24.3%, 0.001), but not A3C (58.5% vs. 40.0%, p = 0.28). CONCLUSIONS: Intraoperative TTE-guided minimalist TAVR either misses nearly half of ≥mild PVR or underestimates PVR by ≥1 grade when compared to predischarge TTE. Posterior PVR jets are more likely to be missed. Transesophageal echo guidance may help minimize missing PVR. Further studies are warranted.

OBJECTIVES: To compare outcomes in Sapien 3 Ultra (S3U) transcatheter aortic valve replacement (TAVR) with extreme annular undersizing (EAU) versus nominal annular sizing (NAS). BACKGROUND: The Edwards S3U valve has reduced paravalvular leak (PVL) in TAVR but outcomes remain unknown in extremely undersized anatomy. Implanting a smaller S3U valve may facilitate future redo-TAVR but risk compromising hemodynamics. METHODS: From December 2019 to July 2021, 366 patients with native aortic stenosis underwent S3U TAVR. Patients with EAU (annular areas >430 mm2 for 23 mm or >546 mm2 for 26 mm) were compared to NAS (338-430 mm2 for 23 mm or 430-546 mm2 for 26 mm). In-hospital and 30-day outcomes, and redo-TAVR feasibility were determined. RESULTS: There were 79 (21.6%) EAU patients, with more bicuspid (p = 0.0014) and ≥moderate annular/left ventricular outflow tract calcification (p < 0.001). The EAU group had less annular oversizing than NAS group (23 mm: -8.2 ± 2.6% vs. 4.0 ± 7.0%, p < 0.001; 26 mm: -8.9 ± 2.2% vs. 6.7 ± 6.9%, p < 0.001), more balloon overfilling (71.3% vs. 11.6%, p < 0.001), and postdilatation (15.0% vs. 5.8%, p = 0.016). No differences were found in in-hospital or 30-day mortality and stroke (p > 0.05). Mild PVL (13.4% EAU vs. 11.5% NAS, p = 0.56) and mean gradients (23 mm: 13.0 ± 4.5 vs. 14.1 ± 5.4 mmHg, p = 0.40; 26 mm: 11.4 ± 4.1 vs. 11.5 ± 3.9 mmHg, p = 1.0) were similar at 30 days. Had the EAU group undergone NAS with the larger Sapien 3/S3U, by computed tomography analysis simulating 80:20 or 90:10 target implant depth, 33.3%-60.9% (vs. 4.3%-23.2%) would not be feasible for redo-TAVR due to high risk of coronary obstruction. CONCLUSIONS: In this first report of EAU with S3U TAVR, similar excellent short-term outcomes can be achieved compared to NAS, and may preserve future redo-TAVR option.

OBJECTIVES: We assessed the impact of conventional delivery system (DS) insertion technique on "Hat-marker" orientation/commissural alignment in patients who underwent transcatheter aortic valve replacement (TAVR) in the Evolut Low Risk Trial CT substudy versus a modified technique. BACKGROUND: Unlike surgical aortic valve replacement, where alignment of the surgical valve commissures with native commissures can be achieved virtually 100% of the time, commissural alignment during TAVR is not achieved consistently. This may subsequently impact the feasibility of both coronary access and reintervention after TAVR. METHODS: "Hat-marker" orientations during deployment were characterized as outer curve (OC), center front (CF), inner curve, and center back. Severe commissure-to-CA overlap was 0-20°. "Hat-marker" orientations and CA overlap were compared to 240 patients from a single center using the modified 3-o'clock flush port DS technique. RESULTS: In the CT substudy in which conventional DS insertion was performed (flush port at 12 o'clock); 154/249 had both analyzable CT and procedural fluoroscopy to validate "Hat-marker" to C-tab/commissural orientation. On post-TAVR CT, Evolut valve commissural orientation and coronary artery (CA) ostia were identified. Compared to conventional DS technique in the CT substudy, the modified technique had higher rates of "Hat-marker" at OC/CF orientation, improved commissural alignment and reduced severe CA overlap; (left main, 14.2 vs. 27.9%; right coronary artery, 11.7 vs. 27.3% both, 5.0 vs. 13.6%; 1 or both CA, 20.8 vs. 41.6%, all p < 0.01). CONCLUSIONS: The modified technique improved initial "Hat-marker" orientation during Evolut deployment and resulted in better commissural alignment and reduced CA overlap.

BACKGROUND: Urgent transcatheter aortic valve implantation (TAVI) is a feasible option for aortic stenosis (AS) patients with decompensated heart failure (HF) and cardiogenic shock (CS) as compared to the more traditional urgent balloon aortic valvuloplasty (BAV). OBJECTIVES: We conducted a retrospective analysis to compare risk and cause of readmission in these two high-risk groups. METHODS: Nationwide Readmission Database (NRD) 2011-2014 was retrospectively analyzed to identify patients with AS having either urgent TAVI or urgent BAV using appropriate ICD-9 codes. Propensity scores were used to match patients with urgent TAVI as compared to patients with urgent BAV. Statistical analysis was performed using the Stata 15.1 software. RESULTS: We identified a weighted sample of 6,670 patients with urgent BAV and 6,964 patients with urgent TAVI. The all-cause 30- and 90-day readmission was lower in the urgent TAVI group compared to urgent BAV (15.4 vs. 22.5%, (aHR): 0.92 [0.90-0.95] p < .001). 30-day readmission due to CV cause and HF was also lower in the urgent TAVI group (aHR, 0.93: p < .001 and aHR, 0.98: p = .040, respectively). The 30-day gastrointestinal (GI) bleed readmission rate was three times higher in urgent TAVI group (aHR, 3.00:95% CI (1.23-7.33), p = .016), but was not statistically significant at 90-days. Cardiac causes of readmission were the predominant cause of readmission in both groups, but more pronounced in urgent BAV group (60.3 vs. 40.5%, p < .001). CONCLUSION: Urgent TAVI appears beneficial in patients with AS and decompensated HF or CS driven by roughly 10 and 25% reductions in overall readmissions at 30 and 90 days, and marked reductions in reintervention, although offset partially by higher risk of readmission due to GI bleeding at 30 days.

PURPOSE OF REVIEW: Accurate imaging of the aortic root during valve implantation is crucial for proper prosthesis positioning during TAVR. The purpose of this review was to determine if routine use of the cusp-overlap view should be adopted for self-expanding valves. RECENT FINDINGS: The use of the cusp-overlap view with the Evolut, Portico, ACURATE neo/neo2, and JenaValve systems is associated with lower post-procedural new permanent pacemaker implantation rates when compared with the standard 3-cusp view, presumably due to more precise valve implantation relative to the conduction system by the non-coronary cusp. By elongating the left ventricular outflow tract and accentuating the right-non commissure in the center of the fluoroscopic view, the cusp-overlap technique allows operators to more precisely control the prosthesis implant depth during self-expanding valve deployment. While the early experience with this approach in Evolut TAVR has been promising, the results of larger studies with longer follow-up across multiple self-expanding systems are warranted.

BACKGROUND: To describe baseline characteristics and outcomes in the largest known registry of advanced heart failure (HF) patients receiving continuous outpatient intravenous inotrope therapy. Studies evaluating the use of outpatient inotropes for palliation or as a bridge to advanced therapies were performed before current guideline directed medical and device therapy (GDMDT). There are limited data on the modern experience using outpatient inotrope (OI) therapy. STUDY QUESTION: We aimed to study current use and outcomes of OI. STUDY DESIGN: Retrospective database analysis. MEASURES AND OUTCOMES: From 2015 to 2017, 1540 advanced HF patients in a largess nationwide registry received OI with either milrinone or dobutamine. Baseline characteristics of 1149 patients data were retrospectively reviewed. Unadjusted Kaplan-Meier survival estimates censored at the time of transplant or mechanical circulatory support were reported. RESULTS: Of 1149 patients, more patients were treated with milrinone than dobutamine (64.6% vs. 35.4%). Regardless of the indication for OI, estimated 1 and 2-years survival was 61.8% and 41.6%, respectively. Milrinone use was associated with a greater 1-year survival than dobutamine (70.7% vs. 46.2%, P < 0.0001). The superiority of milrinone over dobutamine extended to all indications for OI, including bridge to transplant (85.9% vs. 71.3%, P < 0.0001), bridge to mechanical support (91.4% vs. 71%, P = 0.001), and palliation (73.6% vs. 63.3%, P < 0.001). After adjusting for indication, age, gender and weight, milrinone was associated with lower mortality than dobutamine (HR 0.50, 95% CI 0.39-0.64, P < 0.0001). CONCLUSIONS: In the largest dataset of HF patients receiving OI, survival on OI for palliation in the current era of GDMDT is significantly higher than previously reported. Compared with dobutamine, milrinone was associated with improved survival in all cohorts.

OBJECTIVES: We report our multicenter experience on continuous hemodynamic monitoring using exclusively the steerable guide catheter (SGC) during MitraClip repair. BACKGROUND: Left atrial pressure (LAP) and V-wave are useful to evaluate MitraClip repair but no simple method of continuous monitoring exists. METHODS: From 11/2016 to 8/2017, 74 patients from four centers with symptomatic moderate-severe to severe mitral regurgitation (MR), underwent MitraClip NT repair with continuous hemodynamic monitoring via the SGC. Real-time LAP/V-wave changes were compared with transesophageal echocardiography (TEE). When mitral stenosis was suspected, transmitral gradients were verified by invasive hemodynamics. Clinical and echocardiographic outcomes were determined. RESULTS: Mean age was 78 ± 10 years and STS score 9.1 ± 11.0%. Pathology included leaflet prolapse/flail (45%), restriction (35%), and mixed (20%). Number of clips averaged 1.7 ± 0.7 per case. There was a significant reduction in LAP (21 ± 10 to 15 ± 7 mmHg, P < 0.0001) and V-wave(37 ± 19 to 24 ± 10 mmHg, P < 0.0001) post MitraClip, but the decrease was less in patients with atrial fibrillation (P < 0.05). Transmitral gradient significantly increased from 2.0 ± 1.2 to 4.0 ± 1.7 mmHg (P < 0.0001). Paradoxical increases in LAP and V-wave despite MR reduction were observed in three cases requiring MitraClip repositioning or retrieval to avoid stenosis. Follow-up averaged 5.0 ± 2.9 months and was 100% complete. KCCQ improvement was significant and MR reduction to <1+ was 67% and <2+ was 93% at 30 days. CONCLUSIONS: Continuous hemodynamic monitoring using the SGC complements TEE to assess and optimize MitraClip repair in real-time. Further validation is necessary but this feature may be part of future MitraClip and other transcatheter mitral repair systems.

Transcatheter aortic valve replacement (TAVR) has undergone significant advancements in the last two decades, expanding its indications and refining transcatheter heart valve (THV) and delivery system designs to improve procedural success and patient outcomes. This review focuses on the Navitor™ valve, a third-generation intra-annular Portico™ valve (Abbott Structural Heart, St Paul, MN, USA) designed to address TAVR complications, particularly paravalvular leak (PVL). We present an overview of the Navitor™ system, comparing it to the first-generation Portico™ THV in terms of THV design, key iterations and clinical outcomes. The Navitor™ THV introduces two key refinements-a protective outer sealing skirt and a more flexible delivery system. These enhancements have led to a significant reduction in 30 day PVL rates, from 6.3% with the first-generation Portico™ to 0% with the Navitor™ system. Additionally, the Navitor™ system exhibited lower rates of severe bleeding (27.3% versus 13.1%) and major vascular complications (5.8% versus 0.7%) compared with the first-generation Portico™. The Navitor™ valve represents a promising advancement in TAVR technology, with notable reductions in complications such as PVL, severe bleeding, and major vascular issues, compared with its predecessor. While further research is needed to assess long-term durability, these results underscore its potential benefits in enhancing patient outcomes and reducing complications. This review provides insights into the evolving landscape of TAVR technology and its quantifiable impact on patient care.
RESUMO
BACKGROUND: The role of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) who subsequently undergo transcatheter aortic valve replacement (TAVR) remains uncertain. Therefore, we conducted this study to assess the association of PCI before TAVR with mortality and cardiovascular outcomes. METHODS: We used the TriNetX database (Jan 2012 - Aug 2022) and grouped patients into PCI (3 months or less) before TAVR and no PCI. We performed propensity score matched (PSM) analyses for outcomes at 30 days and 1 year. RESULTS: Of 17,120 patients undergoing TAVR, 2322 (14 %) had PCI, and 14,798 (86 %) did not have PCI before TAVR. In the PSM cohort (2026 patients in each group), PCI was not associated with lower all-cause mortality at 30 days (HR: 1.25, 95 % CI: 0.82-1.90) or 1 year (HR: 1.02, 95 % CI: 0.83-1.24). Frequency of repeat PCI after TAVR was low in both no PCI vs. PCI (2.4 % vs. 1.2 %) at 1 year; PCI was associated with a lower rate of repeat PCI (HR: 0.49, 95 % CI: 0.30-0.80). Sensitivity analysis revealed an E-value of 3.5 for repeat PCI (E-value for lower CI for HR: 1.81). PCI was not linked to reductions in MI, heart failure exacerbation, all-cause hospitalization, major bleeding, or permanent pacemaker/implantable cardioverter defibrillator. CONCLUSION: This analysis showed that PCI prior to TAVR was not associated with improvement in all-cause mortality. However, PCI was associated with a reduced rate of repeat PCI at 1 year.

BACKGROUND: SAPIEN3 (S3) is a ubiquitous redo-transcatheter aortic valve (TAV) replacement alternative for degenerated Evolut valves, but S3 sizing for S3-in-Evolut remains unclear. We sought to compare the impact of in vivo computed tomography (CT)-sizing on redo-TAV feasibility for S3-in-Evolut with traditional bench-sizing. METHODS: CT scans of 290 patients treated using Evolut R/PRO/PRO+ between July 2015 and December 2021 were analyzed. S3-in-Evolut was simulated using S3 outflow/neoskirt plane (NSP) at node-6, -5, and -4. CT-sizing for S3 was determined by averaging 4 areas of the Evolut stent frame at NSP level and 3 nodes below. Redo-TAV was deemed feasible if the NSP was below the coronaries, or the narrowest valve (virtual S3)-to-aorta distance was >4 mm. Risk of prosthesis-patient mismatch was estimated using predicted indexed-effective orifice area. RESULTS: Compared with bench-sizing, CT-sizing yielded smaller S3 size in 82% at node-6, 81% at node-5, and 84% at node-4. Factors associated with CT-sizing less than bench-sizing were larger index Evolut size, underexpansion of index Evolut, and shallower implant depth (all P<0.05). CT-sizing increased redo-TAV feasibility by +8% at node-6, +10% at node-5, and +4% at node-4. Redo-TAV feasibility increased with annulus size, sinotubular junction dimensions, coronary heights, index Evolut size, deeper Evolut implant depth, and lower NSP levels (all P<0.05). CT-sizing had a slightly higher estimated risk of severe prosthesis-patient mismatch (9% at node-6, 7% at node-5, and 6% at node-4), which could be mitigated by changing the NSP. CONCLUSIONS: CT-sizing for S3-in-Evolut is associated with higher feasibility of redo-TAV compared with bench-sizing, potentially reducing the risk of excessive oversizing and S3 underexpansion. Further validation using real-world clinical data is necessary.

BACKGROUND: Prior studies investigating the impact of residual mitral regurgitation (MR), tricuspid regurgitation (TR), and elevated predischarge transmitral mean pressure gradient (TMPG) on outcomes after mitral transcatheter edge-to-edge repair (TEER) have assessed each parameter in isolation. We sought to examine the prognostic value of combining predischarge MR, TR, and TMPG to study long-term outcomes after TEER. METHODS AND RESULTS: We reviewed the records of 291 patients who underwent successful mitral TEER at our institution between March 2014 and June 2022. Using well-established outcomes-related cutoffs for predischarge MR (≥moderate), TR (≥moderate), and TMPG (≥5 mm Hg), 3 echo profiles were developed based on the number of risk factors present (optimal: 0 risk factors, mixed: 1 risk factor, poor: ≥2 risk factors). Discrimination of the profiles for predicting the primary composite end point of all-cause mortality and heart failure hospitalization at 2 years was examined using Cox regression. Overall, mean age was 76.7±10.6 years, 43.3% were women, and 53% had primary MR. Two-year event-free survival was 61%. Predischarge TR≥moderate, MR≥moderate, and TMPG≥5 mm Hg were risk factors associated with the primary end point. Compared with the optimal profile, there was an incremental risk in 2-year event-rate with each worsening profile (optimal as reference; mixed profile: hazard ratio (HR), 2.87 [95% CI, 1.71-5.17], P<0.001; poor profile: HR, 3.76 [95% CI, 1.84-6.53], P<0.001). Echocardiographic profile was statistically associated with the 2-year mortality end point (optimal as reference; mixed profile: HR, 3.55 [95% CI, 1.81-5.96], P<0.001; poor profile: HR, 3.39 [95% CI, 2.56-7.33], P=0.02). CONCLUSIONS: The echocardiographic profile integrating predischarge TR, MR, and TMPG presents a novel prognostic stratification tool for patients undergoing mitral TEER.

Transcatheter aortic valve replacement (TAVR) has become more common than surgical aortic valve replacement since 2016, with over 200,000 procedures globally each year. As patients increasingly outlive their TAVR devices, managing these cases is a growing concern. Treatment options include surgical removal of the old TAVR device (transcatheter aortic valve [TAV] explant) or implantation of a new transcatheter aortic valve (redo TAV). Redo TAV is complex because of the unique designs of TAV devices; compatibility issues; and the need for individualized planning based on factors such as implant depth, shape, and coronary artery relationships. This review serves as a comprehensive guide for redo TAV, detailing the design characteristics of TAV devices, device compatibility, standardized terminology, and a structured approach for computed tomography analysis. It aims to facilitate decision making, risk identification, and achieving optimal outcomes in redo TAV procedures.

BACKGROUND: Pulmonary hypertension (PH) and secondary mitral regurgitation (MR) are associated with adverse outcomes after mitral transcatheter edge-to-edge repair. We aim to study the prognostic value of invasively measured right ventricular afterload in patients undergoing mitral transcatheter edge-to-edge repair. METHODS AND RESULTS: We identified patients who underwent right heart catheterization ≤1 month before transcatheter edge-to-edge repair. The end points were all-cause mortality and a composite of mortality and heart failure hospitalization at 2 years. Using the receiver operating characteristic curve-derived threshold of 0.6 for pulmonary effective arterial elastance ([Ea], pulmonary artery systolic pressure/stroke volume), patients were stratified into 3 profiles based on PH severity (low elastance [HE]: Ea <0.6/mean pulmonary artery pressure (mPAP)) <35; High Elastance with No/Mild PH (HE-): Ea ≥0.6/mPAP <35; and HE with Moderate/Severe PH (HE+): Ea ≥0.6/mPAP ≥35) and MR pathogenesis (Primary MR [PMR])/low elastance, PMR/HE, and secondary MR). The association between this classification and clinical outcomes was examined using Cox regression. Among 114 patients included, 50.9% had PMR. Mean±SD age was 74.7±10.6 years. Patients with Ea ≥0.6 were more likely to have diabetes, atrial fibrillation, New York Heart Association III/IV status, and secondary MR (all P<0.05). Overall, 2-year cumulative survival was 71.1% and was lower in patients with secondary MR and mPAP ≥35. Compared with patients with low elastance, cumulative 2-year event-free survival was significantly lower in HE- and HE+ patients (85.5% versus 50.4% versus 41.0%, respectively, P=0.001). Also, cumulative 2-year event-free survival was significantly higher in patients with PMR/low elastance when compared with PMR/HE and patients with secondary mitral regurgitation (85.5% versus 55.5% versus 46.1%, respectively, P=0.005). CONCLUSIONS: Assessment of the preprocedural cardiopulmonary profile based on mPAP, MR pathogenesis, and Ea guides patient selection by identifying hemodynamic features that indicate likely benefit from mitral-transcatheter edge-to-edge repair in PH or lack thereof.

Background: Increased left atrial pressure (LAP) has been associated with adverse outcomes after mitral transcatheter edge-to-edge repair (M-TEER). We sought to evaluate outcomes based on differences in post-procedural LAP measured after final clip deployment. Methods: We included consecutive patients who underwent M-TEER at our institution between 2014-2022 with LAP monitoring. Patients were stratified into 3 groups according to tertiles of post-TEER mean LAP. Outcomes were assessed using Kaplan-Meier analysis and Cox proportional hazard models. Results: We included 273 patients (mean age 76.8±10.8 years, 42.5% women, 78.4% Caucasian). The mean post-TEER LAP was 8.7±1.7 mmHg in tertile 1 (N=85), 14.4±1.6 mmHg in tertile 2 (N=95), and 21.9±3.8 mmHg in tertile 3 (N=93). In comparison with tertile 1, both tertiles 2 and 3 were associated with increased risk of all-cause mortality or heart failure hospitalization at 2 years (adjHR 2.27, 95% CI 1.25-4.12; and adjHR 3.00, 95% CI 1.59-5.64 respectively). Among patients with primary MR, higher LAP was associated with increased risk of 2-year all-cause mortality or heart failure hospitalization [tertile 2 vs. 1: adjHR 3.00, 95% CI 1.37-6.56; and tertile 3 vs. 1: adjHR 5.52, 95% CI 2.04-14.95). However, in patients with secondary MR, neither being in tertile 2 (adjHR 1.53; 95% CI 0.55-4.24), nor tertile 3 (adjHR 2.18; 95% CI 0.82-5.77) were associated with the composite outcome compared with tertile 1. Any degree of LAP reduction following M-TEER was associated with lower mortality or heart failure hospitalization compared with no LAP reduction (adjHR 0.59; 95% CI 0.39-0.88). Conclusions: Elevated LAP after M-TEER was associated with increased 2-year risk of mortality or heart failure hospitalization. Exploration of reasons for elevated LAP after M-TEER, and ways to lower it warrant further investigation.
RESUMO
3-dimensional (3D) intracardiac echocardiography (ICE) is emerging as a promising complement and potential alternative to transesophageal echocardiography for imaging guidance in structural heart interventions. To establish standardized practices, our multidisciplinary expert position statement serves as a comprehensive guide for the appropriate indications and utilization of 3D-ICE in various structural heart procedures. The paper covers essential aspects such as the fundamentals of 3D-ICE imaging, basic views, and workflow recommendations specifically tailored for ICE-guided structural heart procedures, such as transeptal puncture, device closure of intracardiac structures, and transcatheter mitral and tricuspid valve interventions. Current challenges, future directions, and training requirements to ensure operator proficiency are also discussed, thereby promoting the safety and efficacy of this innovative imaging modality to support expanding its future clinical applications.
